The function and purpose of Relay.

A relay represents a switch that can be used electrically. Electromechanical relays are the most prevalent types on the market. They perform their functions by turning on electromagnets that pull the entire set of contacts to open or close circuits. Relays also help you to perform your GMC C2500 logical car functions and inputs. If your GMC C2500 doesn't start when you activate the ignition, and if the engine light is unable to switch "ON" and "OFF", it is an indication that the main relay is broken. You can repair it, or buy a new one if you'd like a faster solution.
